Over the counter stuff is a waste of money. Bi carb in water every couple of hours works a treat, but you do sound like you should be seen by a doctor. Don't leave a UTI if you are passing blood! it wont go away, just come back worse whilst probably doing more damage!

Sorry about the jargon...Glad you are going to get yourself checked out.Recurring UTIs may cause scarring of the kidneys which over time can affect your kidney's filtration function which has all sort of knock-on effects (blood pressure, kidney failure etc). 'Tis not common, most simple cases of cystitis, more often in women, are sore and horrible but do not cause harm necessarily.

Btw, not every I-need-to-go-all-the-time-and-it-hurts episode is always an infection. Just to make things even more confusing.Bicarb in water changed urine's acidity, makes passing water less painful and can make the 'environment' less inviting for bugs to multiply.

I've only had one UTI, it led to a kidney infection and temperature of 41 degrees. Go home, rest, drink lots and lots of fluid - water not just juice - get antibiotics if necessary. Your health is more important than your job.
